Australian explorer AuKing Mining (ASX: AKN) has unearthed shallow copper mineralisation about 700m north of its Sandiego deposit within the Koongie Park copper-zinc project in Western Australia.

The discovery follows assays from one shallow reverse circulation and two diamond drill holes completed during an initial campaign at the project.

One of the holes returned best results of 5m at 1.37% copper from 50m and 2m at 1.71% copper from 85m and presents an opportunity for a largely-untested 700m target zone to be delineated between the main area of drilling at Sandiego and the new discovery.

The water bore hole was located 700m north of a known mineralised zone at Sandiego in an area where no previous drilling activities have identified copper or other metals.

Drilling was terminated at 102m where good flow rates were achieved, highlighting the possibility of further copper mineralisation at depth.

The two intervals of copper mineralisation displayed the now-typical Sandiego geochemical association with elevated cobalt and cerium-lanthanum-yttrium grades.

Assays from two holes at Sandiego were 11m at 2.96% copper, 0.89% zinc, 4g/t silver and 342 parts per million cobalt from 395m, including 4.35m at 6.09% copper, 0.68% zinc, 9g/t silver and 491ppm cobalt from 401m; and 13.1m at 2.45% copper, 0.06% zinc, 4g/t silver and 302ppm cobalt from 455m including 8.7m at 2.96% copper, 0.08% zinc, 5g/t silver and 405ppm cobalt from 455m.

The company said these holes would assist its efforts to identify mineralised extensions at Sandiego at greater depths and further north than previously established.

Known mineralisation

Chief executive officer Paul Williams confirmed the new results could extend Sandiego’s known mineralisation at depth.

“Combined with further high-grade copper intersections from the latest deep drill holes, we are clearly providing the basis to extend the existing known resources,” he said.

“More generally, we continue to make good progress with drilling at Koongie Park and look forward to providing further assay results before year end.”

Koongie Park remains significantly underexplored at depth and along strike and highly-prospective for further VMS (volcanogenic massive sulphide) base metal mineralisation discoveries.

AuKing has identified multiple drill targets to expand on existing known resources at the Sandiego and Onedin deposits, which remain open at depth and to the south.
